In this paper, Ti(C,N)-based nano cermets were prepared by nano particles, and the effect of VC addition on the microstructure and properties of Ti(C,N)-based nano cermets was investigated. The results showed that there existed black-core grayish-rim structure as well as gray-core grayish-rim structure in VC-doped Ti(C,N)-based nano cermets. With the increase of VC addition, the number of gray cores increased, the lattice parameter of Ti(C,N) phase increased, the grain size decreased, the hardness and fracture toughness of Ti(C,N)-based nano cermets were enhanced, and nearly full densification could be achieved. However, excessive addition of VC to 1 wt% resulted in slight decrease in hardness and fracture toughness. Some deep dimples were found in the fracture surface of cermets with VC addition, which corresponded to ductile fracture.
